Another sadistic women's prison film from the director of Ilsa, the Wicked Warden and Barbed Wire Dolls, this exploitation film posits a group of revolutionaries led by Karine Gambier thrown into a South American jail. Howard Vernon plays the staff torture specialist, Dr. Costa, who manages to extract information from Gambier, necessitating an escape by the women to warn their compatriots. Plenty of sex and violence is featured for the raincoat crowd, while Franco cultists will delight in Vernon's wonderfully sinister performance as the prison doctor.
